There is an absence of quantitative criteria and definitions for unusual or anomalous mortality events involving birds, often referred to as “wrecks”. These events most commonly involve seabirds, although terrestrial bird wrecks have also been documented. Typically, the peer-reviewed literature investigating wreck events lacks the details necessary to further our understanding of the circumstances and potential causes of these events. This study reviewed the peer-reviewed literature for wrecks involving Ardenna seabirds (shearwaters), and included grey literature and data collected by citizen science (community) groups. Our results showed a significant time-lag between wreck events and when the data was published in the peer-reviewed literature, which did not occur in the grey literature. Both the grey and peer-reviewed literature were often skewed towards reporting larger wreck events, with only the citizen science dataset capturing smaller wrecks. We outline a proposed framework for reporting mortality events, including the use of quantitative categories to document the numbers of birds involved and taxon-specific thresholds. In doing so, we aim to establish a framework to aid in the quantitative reporting and analyses of future seabird wrecks.

报告海鸟大规模死亡（残骸）事件的拟议框架

对于涉及鸟类的异常或异常死亡事件（通常称为“残骸”），缺乏定量标准和定义。这些事件最常涉及海鸟，尽管也有陆上鸟类残骸的记录。通常，调查沉船事件的同行评审文献缺乏必要的细节来进一步了解这些事件的情况和潜在原因。本研究回顾了涉及阿登纳海鸟（海鸥）沉船的同行评议文献，包括灰色文献和公民科学（社区）团体收集的数据。我们的结果显示，沉船事件与数据在同行评审文献中发表之间存在显着的时间滞后，而灰色文献中没有出现这种情况。灰色文献和同行评议文献通常都倾向于报道较大的沉船事件，只有公民科学数据集捕获较小的沉船事件。我们概述了报告死亡事件的拟议框架，包括使用定量类别来记录所涉及的鸟类数量和特定分类阈值。为此，我们的目标是建立一个框架，以帮助对未来海鸟残骸进行定量报告和分析。
